The Cortex Map

Each focus mode nudges a different cognitive network.

Deep Work

Dorsolateral prefrontal cortex (focus & control)
Creative

Default mode network (ideas & connections)
Learning

Hippocampus (memory & new skills)
Problem-Solving

Frontal-parietal network (logic & decisions)
Communication

Language hubs (expression & understanding)

Cortex Lantern is for focus training and habit-building, not medical diagnosis or treatment.

Why Your Brain Needs This

Attention spans are shrinking

The average knowledge worker switches windows about every 47 seconds – long focus blocks are getting rarer.

Your brain's stuck in notification mode

Constant pings keep your cortex in "reactive" mode instead of deep, sustained thinking.

Cortex Lantern gives you practice reps

Short, repeatable sessions help you gradually increase your attention span and reclaim calm focus.

Hi, I'm Sisi 👋

I'm a content creator and digital-first entrepreneur who spends a lot of time on YouTube, Instagram and inside productivity apps.

After years of bouncing between tabs, notifications and "just one more scroll", I realised my focus – and attention span – felt shredded.

Cortex Lantern started as a small experiment to give myself visual proof that my brain could still do deep, calm work – and to make that training feel playful instead of clinical.

Now I'm building it for anyone who lives online: founders, students, creators, and people in busy corporate roles who want to protect their focus, not lose it.

Hopefully you feel that when you use it – and that it helps you as much as it's helped me. 💜
